2013 volvo D13 water temperature

If it holds steady I wouldn't worry about it.....motors are designed to run in a range.....keep and eye on the temps, and when it's too high/low (cold weather and load dependant), then be concerned..

My Mack warms to 170*F, and running loaded I'll see 200-210* before the fans....it's consistent, so I feel it's good

 

Well....what were the temps like before?

I've only driven Macks (2011 and 1989 a few times), and a 2002 Volvo VHD D12 with shot thermostats....I learned what they were like by watching the gauge.

I knew the Volvo had t stat problems when winter hit, and I couldn't get heat running light or empty in the winter. Sitting still blowing feed it would climb to 200* no problem. Both the Macks (one new-ish and one recently rebuilt) hold a "cold temp" (150-170*) and run hotter, but not enough to worry about...

 

175* all the time....loaded/MT/climbing/Flat....

What do you haul and where....


This may be beyond my keyboard diagnostics skill level.....

 

I've had the DEF doser replaced in the Mack twice. Once before I left, and once since I've been back (I quit for 11 months to haul feed), and who knows what computer updates were preformed while they had it. Since I've been back the motor runs consistently hotter, around 190*-200*, but never more than 210.....

Keep an eye on it would be my suggestion....

The book for the truck will have the range....remember that high number
